Irnis Kubat from the Fiber Sensors & Supercontinuum Group (DTU) makes the JOSA B Top 10 Downloads for the second month in a row with his paper:

I. Kubat, C.S. Agger, P.M. Moselund and O. Bang
“Mid-infrared supercontinuum generation to 4.5 um in uniform and tapered ZBLAN step-index fibers by direct pumping at 1064 or 1550 nm”
JOSA B 30, 2743 (2013).

http://dx.doi.org/10.1364/JOSAB.30.002743

The detailed numerical paper shows for the first time how to pump directly with a standard commercial erbium laser to get a supercontinuum out past 4 um in ZBLAN  step-index fibers.
